We’ll soon have an official explanation for the Note 7’s overheating and fire-starting problem. JoongAng Ilbo (South Korea) reports Samsung has finally finished its investigation and it’ll reveal the cause later this month. Its engineers had struggled for months to find the source of the problem.

Numerous reports of Note 7 units catching fire forced Samsung to recall the phone in October 2016. It was a significant move considering the financial impact of the decision.

Analysts believe it’s important for Samsung to provide a full explanation if it wants to regain consumer trust.
